Disclosed is a modular fluorescence sensor having the following general formula:
Where Fl is a fluorophore, N is a nitrogen atom, Bd1 and Bd2 are independently selected binding groups, Sp is an aliphatic spacer, and An is an anchor group for attaching the sensor to solid substrates. n=1 or 2, m=1 or 2, x is an integer, and y=1 or 2. The binding groups are capable of binding an analyte molecule to form a stable 1:1 complex. In a preferred embodiment, the Bd1 is R1—B(OH)2 and Bd2 is R2—B(OH)2. R1 and R2 are aliphatic or aromatic functional groups selected independently from each other and B is a boron atom. The present invention also provides methods of synthesizing a modular fluorescence sensor and its use in labeling solid substrates.
本发明公开了一种模块化荧光传感器,其具有以下一般式:其中Fl是荧光团,N是氮原子,Bd1和Bd2是独立选择的结合基团,Sp是脂肪族间隔物,An是将传感器附着到固体基质的锚定基团。n=1或2,m=1或2,x是整数,y=1或2。结合基团能够结合分析物分子形成稳定的1:1复合物。在优选实施例中,Bd1是R1-B(OH)2,Bd2是R2-B(OH)2。R1和R2是独立选择的脂肪族或芳香族官能团,B是硼原子。本发明还提供了合成模块化荧光传感器的方法及其在标记固体基质中的应用。
